IMPROVEMENT IN STOP-MOTION FOR WARPING MAGHINL digi Srigctnlt rtwrrt tuin tips glctrrs lntnit mit mating peut tf tige samt TO ALL WHOM IT MAYCONCERN:

Be it known that I, L. V. RICHMOND, of Brainerd, in the county ofRensselaer, and State of New York, have invented a new and ImprovedStop-Motion for Wurping Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art tc make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecication.

The object of this invention consists in the application of astop-motion to warping machines of that class in which the yarn is woundaround a vertical polygonal rcel. Stop-motions to these machines havenever yct been brought into use, although they Vhave already beenapplied to warping machines'of that class in which the yarn is woundaround a horizontal drum. To this latter kind of machines my inventionwill be a valuable improvement.

My invention consists in the construction and arrangement, within theAsliding-frame on which the heck is arranged, or to an independentstationary box or frame, cf a horizontal cylinder, which is providedwith four or more or less flanges, which are secured at equal distancesfrom each other along the outside of said cylinder, each flangeextending from one end to the other of the cylinder. The latter isconnected by a clutch to another horizontal shaft, which receives itsrevolving motion from a pulley or cog-wheel, and imparts the same to thecylinder by means of the said clutch. The shaft on which the latter issecured slides in its journals, and, when the cylinder is stopped bysome obstacle which comes in contact with one of its flanges, theclutch-shaft, which is revolved continually, is disengaged from thecylinder by means of the said sliding motion, and thereby operating anarrangement whereby the driving-belt isA transferred to the loosepulley, thus stopping the machine. The threads of the yarn pass eachthrough three wire loops, which are held upon the said sliding-frame, orupon the independent box. The central row of these loops consists o"flattened steel drop-wires, which are borne up by the tension of theyarn, and which drop instantaneously as soon as the thread breaks. Asthey are arranged immediately above theaforesaid flanged cylinder, thewire drops down as soon as a thread breaks, and thereby immediatelystops the machine. p

This motion is so very simple and works so perfect and easy, notoccasioning any more friction to the yarn, and not being very expensive,that it will be a great improvement, especially to the warping machineswith vertical reels. A

The device can be applied to old machines as well as to new ones,without materially changing any of the working parts of the same. To thewarping machines with horizontal drums this device will also be veryapplicable, as it is not, in my opinion, nearly as complicated and aptto get out of order as the stop-rnotion which is now used thereon.

In the annexed drawings my invention is completely illustrated- Figure1, sheetl, being a side elevation, partly in section, of a warpingmachine, which .is provided with vertical reel, my device being'attachedto the sliding-frame.

Figure 2, sheet 1, is a plan or top view of 4the same.

Figure 3, sheet 1, is a side elevation of the sliding-frame and post onwhich it moves,` viewed from the side opposite to g. 1.

Figure 4, sheet 1, is a horizontal sectional view of the sliding-box,the piane of section being indicated by the line x, iig. 1.- f

Figure 5, sheet 1, is a similar view as iig. 4, the parts being in adifferent position.

Figure 6, sheet 2, is a vertical longitudinal section of the stationaryapparatus, taken on the line y, lig. 7.

Figure 7, sheet 2, is a plan or top view of the said stationaryapparatus, the covering-plate and drop-wires being removed.

Similar letters of reference indicate like parts.

A. is the'vertical revolving-reel, which is mounted upon the verticalaxis Af It receives its motion from the band a, which passes around thereel A and around a pulley, Z, on the vertical shaft B. The verticalshaft B receives its motion by the belt c from the driving pulley C,which belt c passes around the pulleys ol or d on the shaft B, as seenin tig. 1. The lower pulley d is fixed on the shaft, while the upperpulley d turns loose on the same. The upper end of th'3 shaft B runs ina journal which is secured to a cross-timber, D, which is-supported byan upright post, E, which is shown in figs. 3, 4, and 5. On this uprightslides a weight or block, F, which is supported by a rope, e, which isattached to the weight, passes over a pulley, e', and is wound aroundthe uppcr ond of the shaft A', as seen in fig. 1. To the weight F issecured a horizontal bai-, f, which is connected with a box, G, as seenin figs. 1, 4, and Thus the box moves up and down with the weightF,according to the motion of the rcel, whereby the rope 'e is eitherlengt-hened or shortened. v

The yarn, which is wound around bobbins orspoolsg which are secured to abobbin-frame, g', and which yarn is shown by red lines in the drawings,is guided on its way to the reel A under or over a bar, z, and throughhooks or loops on the wires z' and j, all of which are arranged in thebox G. Instead of the bar L, a. series of wires, which are providedwith' loops, may be arranged, while another bar may be substituted forthe wires j. The threads are placed, as` described, through the loops onthe wires, or under the bars L and j, and also through the loops on theflat-tened steel wires z'. These latter are drop-wires, which are heldup by the tension of the yarn passing through the loops on the wires handy'. The wires z' are made of fiattencd steel, and are provided with ahook at their upper end.- They hang in lslots or holes in the cover ofthe box G, and their lower end is also provided with a hoolr, or ratherit is bent once at a right angle, as seen more particularly in fig. G.Exactly below the row of drop-wires z' is arranged in the box G ahorizontal cylinder or shaft, H, which is provided with four (more orless) flanges ZL', extending from end to end of the said cylinder. Nearthe end of the cylinder is arranged a clutch, K, with rounded'taperingedges, (see figs. Lland 5,) which engages a sliding-clutch, Z, whichmoves loosely on the end of the shaft H, as seen in the drawings. Thissliding-clutch Zis moved by a pinion, m, on the horizontal shaft m',meshinginto a cog, Z, on the clutch Z, the shaft m being mounted onbearings outside of the box G.

A pin, m, which is provided with a forked end, mm, as seen in figs. 2,4, and 5, is pressed gentlyby a spring or cord, n, which will behereinafter described, against the sliding pinion and clutch Z Zi', andthereby engages the clutch Z with the clutch k of the cylinder H, sothat the latter is revolved as the shaft m" receives motion. Y

The cord o gives motion to the shaft m as it passes overa pulley, ZY, onthe shaft B, and over the pulley o on shaft m. The cord o is sustainedand guided by friction-rollers p 1vp" and y* in such a manner that itwill not he stretched or slackened by the up-anddown motion of the boxG, but will always revolve the shaft m uniformly. A cord, n, which issecured to the floor on which the machine stands by a staple, q, andwhich passes in front of the fork m" and behind the pins q between whichthe fork is arranged, (sec lig, 3,) is secured at its upper end to afine spring, r, (sce Fig. 2.) The end of the spring r holds a latch, s,down, which latch, as

vsoon as released from the spring r, releases a bolt. t, which is pulledback by a spiral spring, u, and is connected by a cord, r, to a fork orlight frame, u'. This fra-me w is arranged on the belt e, and as soon asthe bolt t is pulled back by the spring u', and with it the cord e, theframe w is raised and raises also the belt c, thereby placing it uponthe loose pulley d and stopping the motion of the machine. A downwardextension, w/, on the frame w serves as a handle to put the machine inmotion'again, as by pulling on the same the belt c will be replaced uponthe pulley d. Thus, as soon as any one thread breaks, the hookeddrop-wire z', through the eye or loop of which it passes, drops, andengaging one of the flanges Zi on the cylinder H prevents the latterfrom moving. Thereby the rounded off-clutchl will move oli, as showninsfig. 5, (as it cannot stop its motion,) and will press the fork m"against the cord n, thereby releasing the latch s from the spring r, andthus stopping the motion of the machine.

This same arrangement can he applied to the warping machines which areprovided with horizontal drums in place o f the 'vertical reel A. Tilearrangement of mechanism employed in a machine in which the bon thatcarries the square eyes is stationary is illustrated in figs. 6 and Y.In this the reel A" is rotated by means of .a band (not shown) whichpasses over the pulley a on the vertical 'axle B. The latter receivesmotion by means of the bevel gear-wheels y and y form a horizontalshaft, A\, which is hung on cross-bars L, which connect thesupporting-posts M of the stationary box G. The posts M are firmlysecured to the floor, and the box G is by them held so that it cannotmore at all. The horizontal shaft X is driven by a belt, N, which passesover the driving-pulley, (not shown,) and over the pulley [i or d on theshaft X. The latter pulley turns loose on the shaft. I

The bevel geur-wheels yand y are secured to a slotted tube, X', whichslides on the shaft X, and 'is revolved with the shaft by means of apin, Z. A sliding-bar, O, which extends from one end to the other of thebox G, and which is provided with a bifurcatcd lever, P, working in aclutch, P', on thb tube X, serves to direct the motion of` the shaft Xand its appendages. v

All the other parts of the stopping apparatus are exactly like those inthe sliding-box G, with the exception that allthe parts are contained inthe box,'while in the other device the cord yn formed a connectionbetween the box G and the stoppingapparatus on the bar D.

The cylinder H is in this modification provided with flanges h', and theclutch operates in the manner already described, the sliding-clutchZbeing revolved by a pinion, m, on the shaft m', the lutter receivingmotion from l the shaft X by a band, o. The sliding-clutch Z, whenpressed back by the stopping of the cylinder H, operates a slottedsliding-plate, z', which is by a spiral spring, z, pressed against thesliding-clutch, being provided with an upright arm, 2*. When the plate zis moved it operates on the spring r, which holds the latch s in place.

As soon as the springr is moved the latch s disengages the horizontalsliding-bar t, which is at one end provided with a staple, w, wherebythe belt N is held, so that when the bar t is disengaged from the latchs it will he pulled forward bythe spiral spring u, and will therebyshift the belt N upon the loose pulley (Z, thus stopping the machine.

In some cases it is necessary to omit some of the threads, when theywill be cut oft` outside of the slidingframe, z'. e., between the latterand the reel. The threads are then weighted to prevent the hooks 1T fromdropA casse 3 ping. And to provide against a possible stopping of themachine by the dropping oi' those hooks, whichl are not used, I use ametal plate, R, which I slide into one end of the box Gr G as far asnecessary, so as to hold any required number of-the hooks z', andprevent them from dropping upon the cylinder II. This plate R' isclearly shown in iig. 6.

What `I claim as new, and desireto secure by Letters Patent, is

1. I claim the construction and arrangement in the sliding-box G of thecylinder H, with ilanges L, upon which the hooks 'i rest, iu such amanner that their eyes shall be above the upper plate ofthe said box,whereby the threads are easily adjusted, as herein shown and described.

' 2. I claim the sliding-box G, provided `with the anged shaft H, havingthe fixed clutch K and sliding coggedclutch Z Z', in combination withthe pinion m, horizontal shaft m', and pulley ov', arranged and operatedby means of the band a from the shaft B, substantiallyas and for thepurpose herein shown and described 3. I claim the stationary box G',with its appendages,- consisting of the flanged cylinder H,sliding-clutch Z, having arm 2*, sliding-plate springs z and 1', latchs, horizontal sliding-bar t, having staple@ and spring n, operated fromthe shaft X by means of the cord o, substantiallyas herein set forth.

4. I claim the plate R, for sustaining the drop-wires t', and operatingsubstantially as herein shown,

and

described.

5. I claim the c ord n, for the purpose of transferring the motion fromthe forked sliding-bar m to the spring 1', substantially as herein shownand described..

6. I claim the combination of the forked bar m" with the pinsq'q an dcord n, substantially as and for the purpose herein shown and described.
